In his 40 years of staging jam sessions, dating from before his first Jazz At The Philharmonic concerts, Norman Granz created more than a few masterpieces of the genre. This was one of them, an inspired combination of the Oscar Peterson Trio with two trumpeters and a tenor saxophonist. But not just any three horn players; Granz chose Dizzy Gillespie, Clark Terry, and Eddie "Lockjaw" Davis. It is beside the point just what or who set off the incendiary spark that caused the blues "Ali and Frazier" to ignite. The happy fact is that it contains some of the most spectacularly volatile playing ever recorded by any of the participants. The pieces that follow are in the same league.
